do these numbers ring true??

[duke of boots]

I purchased a rebuilt 1966 911 2.0L engine and would like to know if these numbers ring true for the year?
Cylinder - 80ZD3
Heads - K1819B, R90110430304
Piston - 1030784
Distributor - Bosch 0231 159001
Alternator - D120 400 522
Engine No 900943

Does this all appear to be right for year?

Many thanks

The head numbers work.
Piston should be Mahle 80V37 on the inside casting

Thanks Bruce, the piston number I had to get from the top of the piston using an endoscope as engine is complete. The 103 sits above an m and the 0784 is directly below the 'm' marking. The other marking is on the cylinder which is an 'm' above what looks like a three pronged crown???

You ll probably find the correct number inside the piston then.

Cylinder - 80ZD3 - correct

Heads - K1819B, R90110430304 - Correct

Piston - 1030784 - should look like attached pic

Distributor - Bosch 0231 159001 - Correct

Alternator - D120 400 522

Engine No 900943 - A '66 engine should have a S/N starting with 903. S/N 900943 would indicate a 1965 engine

Thanks guys, as engine is still together will have to try and view pistons from below with optics. Tom, thanks for date correction.

Thanks Bill, confirmed tonight with endoscope that i have the piston pictured above. Found the casing numbers which are 133/133. So it looks like a have a pretty original rebuilt motor.
